<![CDATA[ What is nuclear electric propulsion and how is it different from radioisotope thermoelectric generators? ]]>
Nuclear electric propulsion is a technology that uses nuclear reactions to generate electricity, which then powers electric thrusters for spacecraft. This method allows for efficient long-duration space missions, providing higher thrust-to-weight ratios compared to conventional chemical propulsion.
Radioisotope thermoelectric generators (RTGs) convert heat released from the decay of radioactive isotopes into electricity. RTGs have been widely used in space missions, providing reliable power for long durations without the need for sunlight or refueling.
